Integrated Manufacturing Processes
We manage the complete component lifecycle under one roof. From High-Pressure Die Casting (HPDC) of premium aluminum and zinc alloys, to secondary CNC machining achieving ±0.005mm tolerances. Our in-house tooling division strictly supports our casting production, ensuring mold longevity and immediate maintenance without vendor delays.
What they say about us
Real-world feedback from engineering teams regarding our execution of high-pressure casting and tight-tolerance machining.
“Their in-house CNC turning achieved the strict 0.005mm concentricity required for our cast bearing housings. This integrated process eliminated the tolerance stack-up issues we previously had with outsourced machining.”
“We needed an optical-grade cavity on a complex cast bracket. Their sinker EDM hit the Ra 0.1μm spec directly without manual polishing, ensuring precise geometric accuracy and saving weeks.”
“Their multi-axis CNC milling held a ±0.01mm tolerance on our critical O-ring grooves immediately after casting. The included CMM reports provided 100% confidence in the final sealing surfaces.”
Strict Quality Control & Certifications
Quality is engineered into our casting and machining processes. We utilize advanced metrology, including 100% CMM dimensional verification for critical CTQ features and X-ray NDT to detect sub-surface porosity.
We operate strictly under：
IATF16949 – Automotive Quality Management
ISO9001 – Quality Management Systems
ISO14001 – Environmental Management
ISO45001 – Occupational Health & Safety Management
SA8000 – Social Accountability
C2C Certification Participation – Supporting global circular economy initiatives
